Sorry for the hijack but I see that OP never replied so...

I just got this error while install rails as well. It appears right after "Installing ri documentation for actionpack-4.0.4"

As Benjamin above says, it happens after "Installing ri documentation for actionpack-4.0.4"

I think everything is working fine now somehow, I didn't really change anything, just uninstalled and reinstalled ruby and rails. Here's the output though, if that helps anyone.

I was having the exact same issue, installing rails on windows 7 32-bit. I ran gem install rails again and it worked fine.

I would recommend trying again and seeing if it gets through.

I am on a Windows 7 laptop, and also had to run the gem install rails twice.
